Infineon offers VDSL2 chipset

German chip maker Infineon is quick out of the blocks to offer VDSL2 chipset for new ultra-fast broadband service.

German chip maker Infineon Technologies has moved quickly to offer what the company claims is the world's first chipset that is fully compliant with the new high-speed DSL (digital subscriber line) standard approved on Friday.

The specification, called VDSL2 (Very High Bit Rate DSL 2), can deliver as much as 100M bps (bits per second) both upstream and downstream, according to the International Telecommunication Union (ITU), which was in charge of the standardization process.

VDSL2 could be a key enabling technology in combined triple-play services, which consist of VOIP (voice over Internet Protocol), high-speed Internet access and multichannel, interactive TV, Infineon said Friday. The technology offers enhanced long-range loop reach similar to ADSL (Asymmetric DSL) systems, ultra-high data rates over short loops and advanced quality of service features such as dual latency and dual interleaving, the company said.

The Infineon product, called Vinax, offers full backward compatibility to ADSL2+, designed to offer speeds up to 25M bps. Broadband service providers using systems with the Vinax chipset will be able to upgrade their DSL networks gradually by changing line cards in their central offices or street cabinets to VDSL, while users will still be able to use their ADSL2+ modems at home.

Infineon shipped more than 6 million [m] ports based on ADSL2+ in 2004 alone, it said.

It’s easy to set up, it’s compact and quiet when printing and to top if off, the print quality is excellent. This is hands down the best printer I’ve used for printing labels.

Brainstorming, innovation, problem solving, and negotiation have all become much more productive and valuable if people can easily collaborate in real time with minimal friction.

The print quality also does not disappoint, it’s clear, bold, doesn’t smudge and the text is perfectly sized.
